ProGuard在Android上导致SSL握手错误

我的应用程序在没有模糊处理的情况下运行良好（特别是在ProGuard中启用了-dontobfuscate），但一旦启用模糊处理，SSL查询就会失败，并出现以下错误：

javax.net.ssl.SSLHandshakeException: Handshake failed

从外观上看可能是okhttp。您是否尝试添加okhttp proguard规则

-dontwarn com.squareup.okhttp3.**
-keep class com.squareup.okhttp3.* { *;}
-dontwarn okio.

---

根据okhttp版本的不同，如果禁用ProGuard，您可能需要丢失okhttp3上的3

，您可以完成HTTP调用吗？是的，没有问题。具体来说，关闭模糊处理可以消除错误。模糊代码导致上述问题。不知道这有什么负面影响…我以前也犯过同样的错误，但不是一个进步的问题。是我访问的web服务的认证。因此，我不得不在网络通话中绕过该证书。@Ssuuk发布proguard-rules.pro文件的内容。由于我无法在设定的时间限制内对其进行测试，我想我将只对收到的答案进行评分。谢谢你的支持！

-dontwarn com.squareup.okhttp3.**
